(blows) - Cutting us straight and
square line with a circular saw, that can't be too hard can it, or is it? (jazzy music) (logo whooshes) (finger clicks) (bell rings) (saw whirs) (ruler shakes) Whoa! Ugh! (exhales) (wood clatters) Good day, folks. All the Knackers here. Now if you can relate to
what you've just seen, don't panic, just relax, because we've all been
there and done that. So let's kick off the new
year, 2021, on the right foot. Making it the year of the squared cut, by building a quick and easy straight square cutting jig type thingy, that'll have you cutting
like a pro in no time at all. Let's do it! Now, popular and very effective option for cutting a straight and square cut, which a lot of people up for
is the use of a speed square, which is what I'm using here. And as you can see, it
does a pretty good job of cutting a straight and a square line. Now mine's only a little fella,
coming in at seven inches. You can buy them all
the way up to 12 inches, but what if the piece of wood
that you're trying to cut is actually bigger than the
speed square that you have? I'll tell you where you are, you're up the creek without a canoe. And that's where the S.C
1000 makes an appearance. Hang on a sec, was what I
meant to say up the creek without a paddle and not a canoe? Let me know, down below. Yeah, I think it is paddle. Up the creek without a
paddle, sounds right. Or canoe? I need a coffee. Okay, the first thing you need to do is to grab yourself a sheet of ply. (wood drops) Then two aluminium angles, a
handful of pan head screws, and a handle of some description, which really is just an optional extra. And I'll leave a list of those materials with their dimensions
down beneath this video just in case you need to check those out. And while you're here,
make sure you stick around, as a little later I'll be sharing the link to my Eight Essential Circular
Saw Tips For The Beginner, which I think you'll find very useful. Now the benefit of using
plywood for this project, is that off the shelf, plywood comes with a factory finish or a factory edge, which simply means that in the factory the sheets are cut nice and square. As you can see here, just like that, which is really important for
this jig to work properly. Now you can make this jig
basically any size you like, it's all up to you and
we're going to be doing it in five simple steps. The first thing we need to
do with the saw unplugged or the battery removed, is lift the guard and then rest the blade
hard up against the edge of the plywood. Now with the blade hard up
against the edge of the plywood, come around to the back
of the saw's base plate, which is all the way over here. And then with your pencil, mark a line along the back
edge of that base plate, and then do the same thing down the other end of the plywood. (jazzy music) Now with your smaller section of angle, place that on our fresh new marks, just like that. And then come up from the bottom, about a hundred
millimetres or four inches, and then on the back edge, mark that line. Done! Hold the phone folks, I'm making a bit of a change. Instead of coming up the
original 100 millimetres, or four inches, I'm sizing the cut down to 75 millimetres, which is about three inches. Sorry about that. Now with that cutting guide that comes with your circular saw, we need to sit that back
roughly 75 millimetres, or about three inches away from the blade. With the saw set up and raring to go we now need to cut out
this section of plywood. Now there's a very important
reason why I'm doing that and I'll explain why shortly. (saw buzzes) (drill whirs) Next on the agenda, we need to grab the
second length of angle, the one with the larger profile. We'll place that on top of the plywood; hard up against the first piece of angle. Just like that. Then we'll cut that to
length using a hacksaw. Then drive in some screws to
hold that firmly in place. Speaking of driving things, did you hear the one about the two nuns who are driving down a
dark and isolated road in Transylvania? Fair dinkum, how crazy! When all of a sudden a
great big scary vampire jumps out in front of the car. So one nun says to the
other, "Show him your cross." So she winds down a
window, leans out and says, "Oy, get out the way you
toothy git!" (laughs) Yeah, a bit confused. She thought angry cross
and not crucifix cross. Easy mistake to make
under the circumstances. It worked apparently, so all good. Yeah. Can't trust those pesky vampires. No, siree! (saw grinds) (drill whirs) And as you can see now,
we've made ourselves a big beautiful square cutting jig. Now to make this a bit lighter, and to jazz it up a little bit, I might just cut an angle or two on this, give it a bit of a paint
job, and then I'll come back and I'll explain why we cut
out this section of plywood. (saw buzzes) (sander polishes) (paint sprays) Okay, let's just screw this handle on and then we'll go ahead,
give it the big test, see how it goes; exciting. Beautiful! Looks good. - Okay, let's just place the old S.C 1000 on top of the sheet
that we're about to cut, hard up against the bottom. And then we'll have a quick chat about the reasoning behind
that extended section there. This section of angles sits hard up against the bottom of our sheet. Whereas this section of angle extends past the bottom of our sheet. Which simply means that
more of your base plate is in contact with the angle, therefore giving you better
control as you enter the cut. Okay, let's test this square
cutting jig thingy out. First of all, we need to line up the edge of a jig here
to our mark over there. Just like that. Righto, let's go. (saw whirs) Okay, let's see how we went. Fingers crossed everybody,
fingers crossed. Alrighty, here we go. That is looking absolutely perfect. How good's that? Now, that is an absolute little ripper. Great tip, Knackers! Hey, check this out: About two minutes ago on the
scorching hot summers day, I was enjoying a frozen Zooper Dooper and I chipped my front tooth. Look, it's chipped! (chuckles) Not happy. That's gotta be the world's
most expensive Zooper Dooper. Not happy. Not at all. Now if you wanna see more
videos just like that one, make sure you check out my, Eight Essential Circular Saw
Tips For Beginners video, which should be popping up
over there just about now. Hope to see you there shortly. (claps) Alrighty, after all that I've
got to go to the dentist. So till next time be good, be safe, and I'm out of here. Cheers. Can't believe I broke my tooth!
